Why not experiment?  Plot the point (2,7),  Then change the y-coordinate's sign:  (2,-7).  Plot this new point.  How did the location of (2.7) change when you changed the sign of the y-coordinate (7)?

Izracunaj opseg i povrsinu kruga upisanog u kvadrat stranice duljine 8 cm.
Nutka1998 [239]
(In English), your question would state the following:


<span>Calculate the circumference and circumference of the circle entered in a square 8 cm long.
</span>
So when finding the answer this this question, we know that the circumference would be the complete area of a circle.

So, I believe we would want to find what is the radius and the diameter that would make this circumference 8^c^m.

The radius would then be (1.274).

Now in your own language (Croatian).

<span>Dakle, kad pronađemo odgovor na ovo pitanje, znamo da bi opseg bio cjelokupno područje kruga. Dakle, vjerujem da bismo željeli otkriti što je radijus i promjer koji bi ovaj opseg mogao učiniti 8cm. Radijus bi onda bio (1.274).</span>

State if the two triangles are congruent. if they are state how you know.
nlexa [21]
1) The triangles are congruent by SSS.

The two tick marks indicate two pairs of congruent sides; it is evident that the third side is congruent by the way the diagram is drawn - the bases of the triangles are together and appear to be the same length.

2) The triangles are congruent by SAS.

The two pairs of tick marks indicate congruent sides, and their included angles are congruent because they are vertical angles, and vertical angles are always congruent.
